TERRY-LOOM.

SPECIFICATION forming part of Letters Patent No. 327,685, dated October 6, 1885. Application filed February 20, 1884. Serial No. 121,436. (No model.)

To 66% whom it may concern.-

Be it known that we, THOMAS HOLT, J r., of Midland Park, in the county of Bergen and State of New Jersey, and J AMES MELLOR, of

Paterson, in the county of Passaic and State of New Jersey, haveinvented certain new and usefulImpI-ovementsin Terry-Looms, of which the following is a full, clear, and exact description.

The object of our invention is to provide certain new and useful improvements in terrylooms used for weaving Turkish toweling.

The invention consists in various combina tions of parts, as will be fully described and l 5 set forth hereinafter.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a cross-sectional elevation of part of a terry-loom provided with our improvements. Fig. 2 is a plan view of the same. Fig. 3 is an enlarged detail cross'sectional view of the upper part of the lay and the breast-beam. Fig. 4 is a diagram of the fabric, showing the manner in which it is formed. Fig. 5 shows the completed fabric.

The lay A is pivoted at its bottom in the frame B in such a manner as to swing in the vertical plane toward and from the breastbeam 0. The lay is connected by connecting rods to with the cranks 1), formed on a shaft, 0, provided at one end with pulleys or other suitable devices for revolving it and at the opposite end with a gear-wheel, d, which engages with a gear-wheel, 0, having twice the diameter of the gear-wheel (Z, and which is mounted on a shaft, 5 parallelwith the shaft 0, and provided with a pinion, 71 engaging with a pinion, j, on a shaft, 7c, journaled below and parallel with the shaft 9, which pinion j is once and a half the diameter of the pinion h, so that the shaft will revolve once for every three revolutions of the shaft 0.

On the shaft is a cam, D, is mounted, on which rests a lever, E, pivoted in the frame B, the free end of the lever extending below the lay, and the said free end of the lever passes through an aperture in the downwardly 5o projecting shank F of a flat frame, F, held to slide vertically on the front of the laythat is, on the side toward the breast-beam-so that when the shaft is revolved the lever E will be moved up and permitted to descend, thereby moving the frame F up and down on the face of the lay.

The reed G is held at its top in a groove in the bottom of a bar, H, uniting standards H on the lay, and the lower edge of the reed G is held in a groove in the upper surface of a bar, J, held in arecess, J in the rear upper edge of the lay, which bar J is pressed in the direction toward the lay by springs K, secured on the bottom of the lay and having their upper ends held on the said bar J.

Two or more vertical slots, I, extend transversely through the lay, and through the said slots horizontal arms L pass which are pivoted to the bar J, the said arms being each provided in its upper edge with a shoulder, M, adapted to rest against that portion of the face of the lay above the slots 1. The lower edges of the arms L rest on the upper edge of the frame F, as is shown in Fig. 3. At their outer ends the arms L are provided with notches M, adapted to receive the beveled or flattened ends of screws N, screwed through the top of the breast-beam G, the beveled ends of the screws projecting toward the face of the lay.

A suitable shuttle-race is provided in the same manner as in any other lay, and the remaining part of the loom is constructed in the usual manner.

The operation is as follows: \Vhen the cam D does not raise the lever E, the frame re mains lowered, as do also the arms L, and when the lay swings toward the breast-beam the outer ends of the arms L come in contact with the inner ends of the screws N, whereby the arms L will be pushed in the inverse direction of the movement of the lay-that is, in the direction of the arrow b-thereby swinging backward the reed G and preventing the said reed from driving the last weft homethat is, preventing the reed from driving the last weft against the finished edge of the cloth; but if the cam D raises the lever E the frame F will be moved upward and the arms L will be raised so that their shoulders engage with the face of the lay, and the free ends of the arms L will be raised to such an extent that they will pass over the beveled ends of the screws N, and the bar J, or lower part of the reed, will not be pressed in the direction of the arrow b, thus permitting the reed to drive the last weft home.

The loom described is so arranged that for two strokes of the lay the reed is pressed back, and in the third stroke the cam D raises the lever E sothat the arms L will be raised above she ends of the screws N, thus permitting the Weft to be driven homethat is, every third weft is driven home. This is illustrated in Fig. 4, in which m represents the edge of the 310th. At the first stroke of the lay the first weft, a, is not driven home. At the second stroke the second weft, a", is driven against the irst weft, 1/, but nofarther, as the lower edge of :-he reed is pressed in the direction of the arcw b by the screws N; but the third weft, 11. s driven home as the arms L are raised durng this stroke of the lay,- and the Weft a iresses the two preceding wefts a and n along with it, pressing them up against the finished age we of the cloth. The warps will thus 'ortn the loops as shown in Fig. 5.

It is evident that the loom can be so con- :t'ruoted as to drive the second, third, fourth, ifth, or sixth weft home, as may be desired, tud according to the number of loops desired 11 the fabric. The length of the loops is tdjust'ed by means of the screws N, for the 'ar'ther the said screws project from the breastieam the greater will be the distance that the i211 J is swung back, and thus the greater will e the distance between the finished edge of he cloth and the first weft, a. When the lay lrives the wefts home, the bar J is locked in b12108 within the lay by the shouldered arms 1, and does not rely upon any springs to exrt their pressure in driving the wefts home,. he springs K only serving to pull the bar J 11 place. The arms L always have a positive notion, as their shouldered ends rest against he surface of the lay.

Having thus described our invention, what we claim as new, and desire to secure by Leters Patent, is V V 1. The combination, with a loom-frame and ay, of projections 011 the breast beam, a winging reed, pivoted projections on said winging reed, and means, substantially as .escribed, for raising and lowering the proections on the swinging reed to bring them nto or out of line with the projections on the reast-beam, substantially as herein shown nd described.

2. The combination, with a loom-frame and ty, of projections on the breast beam, a winging reed, projections pivoted on the i'wer part of the swinging reed and projecting through the lay, a sliding frame on the lay, and a lever and cam for raising and loweringsaid sliding frame, substantially as herein shown and described.

3. The combination, with the loom-frame, a lay, and mechanism for operating the latter, of a reed having its lower edge adapted to swing toward and from the rear surface of the lay, projections pivoted to the swinging edge of the reed and extending'through slots in the lay toward the breast-beam, projections on the breast-beam, asliding frame on the lay for the purpose of raising the projections pivoted to the reed, a lever. passed through the sliding frame, a cam for raising the said lever, and intermediate mechanism for operating the cam from the lay-operating mechanism, substantially as herein shown and described.

'4. The combination, with the loom-frame, 'a lay, and mechanism for operating the latter, of a feed having its lower edge adapted to swing toward and from the rear surface of the lay, projections pivoted to the swinging edge of the reed and extending through slots in the lay, adjustable projections on the breastbeam, which projections extend toward the lay, a lever and cam for alternately raising and lowering the projections pivoted on the reed, and intermediate mechanism for operating the said cam from the lay-operating mechanism, substantially as herein shown and described.

,5.- The combination, with the loom-frame, a lay, and mechanism for operating the latter, of a reed having its lower edge adapted to swing toward and from the rear surface of the lay, projections L, pivoted to the swing ing edge of the reed and extending through slots in the lay, each of which projections L has a shoulder in its upper edge, projections on the breast-beam, alever and cam for alternately raising and lowering the projections on the reed, and intermediate mechanism for operating the said cam from the operating mechanism of the lay, substantially as herein shown and described.

6. The combination, with the loom-frame and a lay, of the reed G, having its bottom bar, J, adapted to swing toward and from the outer surface of the lay, the springs K, for pressing the bar J toward the lay, the pro jections or arms L, pivoted to the bar J and passing through slots I in the lay, the sliding frame F on the lay, the screws N on the breast-beam, and a lever and cam for automatically raising and lowing the frame F, substantially as herein shown and described.
